5m.

(2)what colours do you have ?

We have the Standing of colour in more than 10 to 20 kinds,such as red,yellow,

green,orange,purple,black,gold ,Silver White, and gray.And the special colour

could be customed by client,and it has MOQ,this MOQ just depends on the actual size of what you request,for example,if you want to custome a special colour on dia 2m balloon,(this special colour is PANTONE),its MOQ should be reach 200pcs,then it could

be customed by that sepecial colour.Additional,the general MOQ is even one pcs if you just want balloon without any printing,or the printing could be the colour near PANTONE tone,but this one pcs balloon's price would be a lot higher than that without

printing balloon.(3)How many watt light can be put inside

For that watt of light,it just depends on the size of balloon,for example,2m balloon use 100w light,and all the balloon we use led light or Halogen light,2m balloon use 1pcs of Halogen,and the 3m is the same,for that 5m balloon,it needs 2pcs of Halogen,or one pcs of big watt Halogen light。

(4)what is the minimum order quantity

As i said before,even one pcs we also could help you to make,if there is no printing,or the printing colour is near Pantone Color,but the price would be lots higher than that no printing one!

(5)how many days it can stay on real without pumping more air or helium in it

If there is no broken problem with that balloon,it could be use by many days,and this hasn't been statisticsed by us,but i could answer you that it could be used for

long long a time!!And the balloon could be prominsed not leak if it is intact.

(6)how it is working with helim or auto inflated what is the material pvs or anything else

Genrally speaking,if you want that balloon to be on air,we use PVC material,and this balloon could be filled by helium or Hydrogen(but we won't suggest to fill Hydrogen,that is dangerous you know.)The other kind is PU coated parachute cloth,this material would be used if you want that balloon to be hang with proof,or make it on the floor.It has built blower could auto inflate,and it needs electricity source for continuous charge!
